Norrie May-Welby (born Bruce Norrie Watson, 23 May 1961[2]) is a Scottish-Australiantranssexual person who pursued the legal status of being neither a man nor a woman, between 2010 and 2014.[3][4][5][6][7] The High Court of Australia ruled in April 2014 that it was in the power of the NSW Registry of Births, Deaths and Marriages to record in the register that the sex of May-Welby was 'non-specific'.

At least two other Australians - both born intersex and including Alex MacFarlane - are known to have birth certificates and/or passports showing an indeterminate or unspecified sex as early as 2003.[8][9][10]

The New South Wales Government Registry of Births, Deaths and Marriages initially recognized May-Welby as being neither male nor female with a registered details certificate stating "not specified" in 2010. However, the Registry rescinded its decision in a formal letter of cancellation on 17 March 2010. In response, May-Welby filed a complaint with the Australian Human Rights Commission and to the Court of Appeal.[14] The Court of Appeal ruled in favour of May-Welby but the Registrar appealed to the High Court. In April 2014 the High Court ruled that it was within the Registrar's power to record in the register that the sex of May-Welby was 'not specific'. The Court found that sex affirmation "surgery did not resolve her sexual ambiguity".[15] In commenting on the four-year battle, May-Welby stated "It was swings and roundabouts, but I’m on Wikipedia now".[16]
